Observation of quasi-steady dark excitons and gap phase in a doped semiconductor
Shangkun Mo, Yunfei Bai, Chunlong Wu +16
Exciton plays an important role in optics and optics-related behaviors and leads to novel correlated phases like charge order, exciton insulator, and exciton-polariton condensation…

Sensitive infrared surface photovoltage in quasi-equilibrium in a layered semiconductor at low-intensity low-temperature condition
Qiang Wan, Keming Zhao, Guohao Dong +10
Benefit to layer-dependent bandgap, van der Waals materials with surface photovoltaic effect (SPV) enable photodetection over a tunable wavelength range with low power consumption.…
